Indeed. Even with the blocker bug list cleared we want to let these changes go through the usual nightly > beta > release phases to make sure we have a chance to catch regressions and minimize risks overall.

As far as CPU’s go, Intel has always had the stronger single-core performance and AMD always the better multi-core performance. Single-core may be looking to change when we see reviews on AMD’s Matisse (Zen 2) CPU architecture this July.

And i’m all for AMD doing better as the graphics and CPU market desperately relies on it. Hopefully Navi and future GPU architectures will be competitive or have advantage over Nvidia GPU’s (or Intel GPU’s once we see their Arctic Sound/Xe architecture released).

We don’t enable WebRender on Linux by default yet, but you can try it out by enabling the “gfx.webrender.all” pref in about:config (works on Nightly, Beta and Dev Edition but not yet on stable, I recommend Nightly to get the latest bug fixes).

I use WebRender on Linux every day on Xorg with various intel integrated GPUs and nvidia (proprietary drivers) and it has worked well for me so far. I don’t know whether you’ll run into issues with AMD hardware but there is a good chance that it’ll work for you too, and if it doesn’t filing bugs will help us close the gap.
